Explanation:
A southern exposure and striking symmetry made
Lulworth Cove,
along the Jurassic Coast of England, planet Earth
a beautiful setting during this December's Solstice.
Five
frames in this dramatic composite view follow the lowest
arc of the Sun, from sunrise to sunset,
during the shortest day of the year.
The solstice arc spans about 103 degrees
at this northern latitude.
Of course, erosion by wave action has produced the cove's
remarkable shape in the coastal limestone layers.
The cove's narrow entrance
is responsible, creating a circular wave diffraction pattern made
clearer by a low sun angle.
